I am thinking about purchasing a laptop computer for a group of people who are beginners (informal sessions). I normally use a desktop and I am unfamiliar with laptop computers. I have been advised that I need a dongle. I have not come across this term before and do not know exactly what dongle is? Is a similair to a memory stick. I have been told you do not need dongles on modern laptops nowadays.
Can someone give me any information on this.
